Phenyl cationic micro-monomer polymer modified block polycarboxylate water reducer
The invention relates to a phenyl cationic micro-monomer polymer modified block polycarboxylate water reducer, which is mainly prepared from the following components: 3 to 7 parts of benzene ring monomers; 5-7 parts of a cationic micro-monomer; 354 to 365 parts of a polyether macro-monomer; 16 to 27 parts of unsaturated dicarboxylic acid; 1.1 to 1.5 parts of an initiator a; 1.8 to 2.2 parts of aninitiator b; 0.7 to 1.1 parts of an initiator c; 1.3 to 1.6 parts of a chain transfer agent; and the balance being water, wherein the total mass of the raw materials is 1000 parts, and the mass fraction is 40%. The block polycarboxylate water reducer is prepared by grafting and copolymerizing the phenyl cationic micro-monomer polymer to the main chain of the polyether macro-monomer, and the waterreducer has the advantages of low cement consumption, good durability, no corrosion to reinforcing steel bars, and efficient particle dispersion performance and retention capacity.
本发明涉及一种苯基阳离子小单体聚合物改性的嵌段聚羧酸减水剂，主要由以下组分制备而成：苯环类单体：3‑7份；阳离子小单体：5‑7份；聚醚大单体：354‑365份；不饱和二元羧酸：16‑27份；引发剂a：1.1‑1.5份；引发剂b：1.8‑2.2份；引发剂c：0.7‑1.1份；链转移剂：1.3‑1.6份；其余为水；原料总质量为1000份，质量分数为40％。本发明以苯基阳离子小单体聚合物接枝共聚到聚醚大单体主链上的方式制备嵌段聚羧酸减水剂，该减水剂水泥使用量低、耐久性好、不锈蚀钢筋、具有高效的颗粒分散性能和保持能力。
